SPECIFICATION forming part of Letters Patent No. 325,610, dated September 1,1885.

Application filed June 27, 1885. (No model.) I

IO which form a part of this specification.

Our invention relates to an improvement in machines for smoothing, polishing, and finishingjapanned,varnished,or painted surfaces upon wood, the object being to produce a I5 machine which shall be efficient and durable in use, of large capacity for work, and simple to construct and easy to operate.

ith these ends in view our invention consists in a machine having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation of a machine embodying our invention. Fig. 2 is a view thereof in end elevation with a portion of the upright broken away. Fig. 3 is a detached view of the bearing; and Figs. 4, 5, 6, and 7 are respectively views of interchangeable rubbers.

As herein shown, A, B, (J, and D are rubbers, each of diti'crent cutting or abrasive surface. These rubbers may be formed of felt, canvas, or of any other material which may be found suitable for the purpose. Each is provided with strips a (I, located upon their upper faces and at. their opposite ends. The rubbers are interchangeably connected through the said strips with a bearing, E, having adjustable and universal joint connection through the 40 frame F, stirrup G, and sleeve H, with a lever,

I, and provided with a chamber, J, perforations K, and with a groove, L, which encircles it. The said lever has universaljoint connect-ion at one end with an upright or support,

5 ill, secured to the frame N of the machine,

while its other and free end is adapted to be connected with a rod, 0, attached toa treadle, P, and with a spring, suspended from above the machine. The lever runs parallel with two ways, R, located one above the other, and

supporting a reciprocating slide. S, provided with a groove, T, and an adjustable gib, U, to

receive the said ways, and with a platform, V, having a longitudinal groove, NV, receiving the adjustable block X, which is provided with a spur, and also receiving the adjustable block Y, which is provided with a pivotal spurred arm, Z, and with a cam, A, for operating the same. The platform of the slide is also provided with ashallow groove, B, collecting the waste water and polishing material, and with a passage, 0, leading from the said groove into a flexible discharge-pipe,1), carried by the slide. The said slide is connected through a pitman, E, with a slotted crank arm, F, which is secured to the shaft G, the same being provided with pulleys H, and a balancewheel, 1', as shown. Figs. 1 and 2 of the drawings show a piece, J, mounted in position for having its surface rubbed down.

Having described the construction of a machine embodying our invention, we will now proceed to set forth the method of its operation.

The blocks K and Y are first adjusted upon the platform or bed of the slide to conform to the length or shape of the pieces to be robbed, which are then separately placed upon the platform and between the blocks and firmly secured in place by operating the cam to force the pivotal and spurred arm into the end of the piece to be rubbed, whereby the same is moved along and engaged with the other block. The abrasive material, in fluid, paste, or powdered form, is applied to the surface to be rubbcd,after which any one of theintcrchangcable rubbers is placed upon such surface. Then the lever is disconnected from the suspensionspring and let down, and the rubber is engaged with the hearing which fits between the strips located upon its upper face. Then the rod connecting with the trcadlc is connected with the lever and the power applied for reciprocating the platform or bed, whereby the piece to be rubbed is rapidly carried forward and back with the surface to be finished or smoothed in contact with the rubber, which is pressed down upon the surface through the rod and treadle, affording a pressure capable of being varied as desired. Then by disconnecting the rod from the lever and lifting the latter the rubber may be replaced by another of different capacity for abrasion. Thus a coarse rubber would be replaced by a liner one, and

so on. As the work progresses, more abrasive material may be added, and of the same kind as was started with,or of different quality; or the abrasive material may be changed when the rubbers are changed, To insure a plentiful supply of water to facilitate the work and to prevent the varnish, lacquer, or japan from heating and blistering, the chamber of the bearing is preferably kept supplied with water,

which feeds through the perforations and thence to the rubber. \Vhen the work is done, the rod is disconnected from the lever, which is then lifted up and connected with the suspended spring, where it is out of the way during the substitution of the piece rubbed for another.

By mounting the bearing in universal bearings it conforms to the plane of the surface to be rubbed, whereby an even surface is secured, while by mounting the lever in universal bearings, as shown, it acquires a capacity not only for being moved vertically, but also laterally to give a wider range of action to the rubber.

By providing for the adjustment ofthe sleeve upon the lever the exposure to the action of the rubber may be varied by arranging for it to lap more at one end of the piece being rubbed than at the other end thereof, whereby one end of the piece may be rubbed more than its other end, as is sometimes necessary in obtaining uniform surfaces upon pieces which are immersed for a surface-coating and then hung up by one end to dry, whereby the material gravitates at the lower end of the piece and forms a thicker coating at such end.

If desired, the interchangeable rubbers may be dispensed with and a rubber attached directly to the bearing, which is provided with a groove for wiring or otherwise securing felt, canvas, or other vehicle for abrasive material to it. If desired, also, the shallow groove collectin g the waste water and polishing material may be dispensed with, and a suitable tray employed in its place. Furthermore, provision for rubbing the pieces more at a certain place or places than at others may be made by conforming the platform of the slide forming the bed of the piece to the requirements of the case. Thus by arranging to lift the piece be ing polished at one end it will be cut away at such point more than elsewhere.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a machine for smoothing, polishing, and finishing japanned, varnished, or painted surfaces upon wood, a rubber, a support for the same, a reciprocating bed adapted to carry the article or object to be rubbed, and devices for securing pressure between the rubber and the article or object being rubbed, substantially as set forth.

2. In a machine for smoothing, polishing, and finishing japanned, varnished, or painted surfaces upon wood, a rubber, a reciprocating bed adapted to carry the article or object to be rubbed, and a support for the rubber constructed for moving the same toward and away from the reciprocating bed, substantially as set forth.

3. In a machine for smoothing, polishing, and finishing japanned, varnished, or painted surfacesupon wood, a rubber, a lever, universal-joint connection between the same and the rubber, and a reciprocating bed adapted to carry the article or object to be rubbed, substantially as set forth.
